Prior to this, terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary terms, and the inventor should appropriately interpret the concepts of the terms appropriately It should be interpreted in accordance with the meaning and concept consistent with the technical idea of the present invention based on the principle that it can be defined. Therefore, the embodiments described in this specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and do not represent all the technical ideas of the present invention. Therefore, It is to be understood that equivalents and modifications are possible.

1 is a schematic block diagram of a vehicle data control system 100 according to an embodiment to which the present invention is applied.

1, a vehicle data control system 100 according to the present invention may include an embedded operating system 110, a vehicle controller 120, a file system 130, and a display 140 .

The embedded operating system 110 serves as an interface between hardware and an application program, and manages resources such as a CPU, a main memory device, and an input / output device. Furthermore, it controls the execution of application programs and manages the storage of data or files. The vehicle controller 120 is a configuration that controls overall operation or state of the vehicle and may be connected to the embedded operating system through vehicle network communication (e.g., CAN communication) to exchange data related to vehicle operation and status .

The file system 130 is a configuration for storing and managing user contents as well as data related to vehicle operation and status. The file system 130 may be configured as a plurality of partitions to prevent user contents from infiltrating the main system in the file system. Here, a case where the file system 130 is composed of three partitions for the sake of understanding the invention will be described.

As shown in FIG. 1, the file system 130 may include three partitions, that is, a first partition, a second partition, and a third partition. Here, the first partition is a memory that is read-only and stores and manages applications and data (hereinafter referred to as " vehicle basic contents ") related to vehicle operation and status. Also, the first partition may be blocked from accessing other partitions to ensure the reliability of the stored data. As such, the first partition can store and manage applications and data related to speed gauges, RPM gauges, warning lights, fuel gauges, and the like on the basis that the stored data can not be changed and access from other partitions is blocked.

The second partition is a memory capable of both reading and writing, and is a configuration for storing and managing the basic contents of the vehicle like the first partition. In addition, the second partition may also be blocked from accessing other partitions in order to secure the reliability of the stored data. However, it is possible to record some data through the preset access path. Accordingly, the second partition can store and manage cluster mileage information, average mileage information, and the like, which are recordable data.

The third partition is a memory capable of both reading and writing, and is a configuration for storing and managing user-supplied applications and data (i.e., user contents). The third partition can not overwrite another partition because access to the other partition is blocked, and even if the third partition is contaminated by viruses, it may not affect other partitions.

The display 140 displays an image according to the execution of at least one of the vehicle basic content and the user content stored in the file system 130. [ As shown in FIG. 1, the display 140 can hierarchically display an image using a multi-layer, that is, at least two layers (a first layer and a second layer). In this case, the first layer may denote an area for displaying an image according to the execution of the vehicle basic contents of the first partition and the second partition, and the second layer may denote an area for displaying an image according to the execution of the user content . In FIG. 1, the display 140 is composed of two layers, but the present invention is not limited thereto. For example, the display 140 may hierarchically display an image using three layers, that is, a first layer, a second layer, and a third layer, corresponding to partitions constituting the file system. Here, the first layer is an area for displaying an application or an image according to the execution of data stored in the first partition, a second layer is an area for displaying an application or an image according to the execution of data stored in the second partition, And the third layer may respectively indicate an area for displaying an image according to the execution of the user content. Furthermore, each layer may be configured to not overlap with another layer. This is to ensure that the layer associated with the user content does not violate the layer associated with the vehicle operation / status requiring reliability.

FIG. 2 is a schematic block diagram of a file system 130 according to an embodiment of the present invention.

The file system 130 may store the data in the partition corresponding to the corresponding vehicle data in consideration of the type of the vehicle data transmitted to the file system 130. [ The file system 130 may further include a data type identification unit 200 and a partition determination unit 210 as well as a first partition 220, a second partition 230 and a third partition 240 have. The partitions 200, 230, and 240 have been described with reference to FIG. 1, and a detailed description thereof will be omitted here.

The data type identification unit 200 is a configuration for identifying the type of the received vehicle data. Vehicle data may be understood as a concept involving applications and data related to the vehicle ' s operation / status as well as user-provided applications and data. That is, the data type identification unit 200 determines whether the received vehicle data is read-only data (hereinafter referred to as Data type A) among applications and data related to the vehicle's driving / (Hereinafter referred to as "data type B") or data corresponding to user contents (hereinafter referred to as "data type C").

The partition determining unit 210 determines a partition in which the vehicle data is stored based on the data type identified by the data type identifying unit 20. [ For example, when the type of the received vehicle data is Data type A, an address of a partition in which read-only data among application and data related to the vehicle's driving / state is stored can be assigned to the corresponding vehicle data. Here, the address may refer to a memory address where vehicle data is stored.

The vehicle data may then be transferred to a partition corresponding to the assigned address and stored and managed. Specifically, when the type of the received vehicle data is Data type A, an address (Address 1) of the first partition is assigned, and the vehicle data may be transferred to the first partition corresponding to Address 1 and stored and managed . As described above, by allocating the partition address in consideration of the type of the vehicle data in the file system, it is possible to prevent the user contents from being transmitted to the first partition or the second partition that requires reliability.

3 is a flowchart illustrating a method of storing data in a partition in consideration of the type of vehicle data in the file system 130 according to an embodiment of the present invention.

First, vehicle data can be received (S300). Here, the vehicle data may include user-supplied applications and data, as well as applications and data related to the vehicle ' s running / status, as seen in Fig.

The type of the received vehicle data can be identified (S310). Specifically, it is possible to identify whether the vehicle data is the application or data (Data type A or Data type B) related to the running / state of the vehicle or the user-provided application or data (Data type C). Further, when the vehicle data is an application or data related to the vehicle's running / state, it is possible to identify whether it is data (A) or read / write data (Data type B).

The partition corresponding to the vehicle data can be determined based on the type of the vehicle data identified in step S310 (S320). Specifically, the partition corresponding to the vehicle data can be determined by assigning a partition address to the vehicle data based on the predetermined table information. Here, the predetermined table information may be stored in the file system 130, which defines the type of vehicle data, the partition address, and the relationship between corresponding partitions. For example, the predetermined table information may be defined as shown in Table 1 below.

NO. Types of vehicle data Partition address Corresponding partition One Data type A Address 1 First partition 2 Data type B Address 2 Second partition 3 Data type C Address 3 Third partition

Referring to Table 1, the predetermined table information defines a partition address allocated according to the type of vehicle data, and also defines a corresponding partition for each partition address.

The received vehicle data may be transferred to the partition determined in step S320, and stored and managed (S330).

4 is a flowchart illustrating a method of displaying an image on a multi-layer basis according to an embodiment of the present invention.

When the ignition switch of the vehicle is turned on (S400), the cluster boot loader is booted (S405), and the first partition and the second partition are loaded (S410). Here, the first partition is a structure for storing and managing vehicle basic contents, and may mean a read-only memory. Also, the second partition may be configured to store and manage the basic contents of the vehicle, like the first partition, or a memory capable of both reading and writing.

Then, an execution code (hereinafter, referred to as a first execution code) indicating an execution command of the vehicle basic content of at least one of the first partition and the second partition may be generated (S415).

An image of the first layer may be generated by executing an application stored in the first partition or the second partition corresponding to the first execution code generated in step S415 (S420).

Similarly, when the cluster boot loader is booted (S405), the third partition may be loaded (S430). Here, the third partition is a structure for storing and managing user contents, which means a memory capable of both reading and writing. The third partition may be loaded at the same time the cluster boot loader is booted. Alternatively, the third partition may be loaded only when receiving a user's loading command for the third partition, since it is an area where user-provided applications and data are stored.

When receiving the user content execution command from the user, the execution code (second execution code) according to the user content execution command can be generated (S435).

In operation S440, an image of the second layer may be generated by executing the user content of the third partition corresponding to the second execution code generated in operation S435.

The images of the first and second layers generated in steps S420 and S440 may be displayed (S425). A method of displaying multi-layer-based images so as not to overlap each other will be described with reference to FIG.

Meanwhile, it is possible to monitor whether there is no error in the execution of the user content and whether there is an error on the generated image of the second layer in parallel with the execution of the user content and the image creation of the second layer (S445) .

If at least one of the monitoring result, the execution error of the user content, and the error of the image of the second layer occurs, the execution of the user content being executed may be terminated (S450). For example, the execution of the user content can be controlled to be terminated by blocking the generation of the execution code according to the user content execution command, that is, the second execution code. Alternatively, it may be controlled using an end code indicating a forced termination instruction of the user content being executed.

5 is a flowchart illustrating a method of displaying a multi-layer-based image in a display control unit according to an embodiment of the present invention.

In the case of displaying a plurality of layers, i.e., a plurality of hierarchical images in one cluster display, it is necessary to control so that a plurality of images do not overlap each other. This is because, if the data relating to the vehicle operation / state to be provided to the user at all times is obscured by the data relating to the user contents, there is a risk to the operating user.

Referring to FIG. 5, the image of each layer generated in step S425 may be resized using the screen size information of the cluster display (S500). Here, the screen size information of the cluster display may include height and width information of the screen. Also, resizing may mean changing the image of each layer to an image of the same size as the cluster display.

Specifically, if the generated image is smaller than the size of the cluster display, the image may be accompanied by an upsampling process. That is, an interpolation filter may be applied to each sample of the generated image to generate an upsampled image. The interpolation filter is preset in the display controller (not shown), and a bi-linear filter, a tap filter, or the like can be adaptively used in consideration of the image quality and complexity of the image. On the other hand, if the generated image is smaller than the cluster display size, the image may be accompanied by downsampling.

Then, the resized image may be down-sized using the size control information of the image (S510). Here, the size control information may mean size information of an image determined within a range in which a plurality of images do not overlap with each other in a cluster display. For example, the size control information may be represented by height and width information of the corresponding image. Alternatively, the size control information may be expressed as a ratio of an area occupied by the image in the cluster display. The size control information may be preset for each image of each layer in the display control unit (not shown) or may be set by user input. In this manner, the images of the respective layers can be downsized using the size control information, so that they can be controlled so as not to overlap each other on the cluster display.

The image downsized in step S510 may be displayed (S520).
